As you are from the UK I guess you are looking at the QP school in Messaid. I don't know much about it but can tell you about working as a teacher for QP in general. In my experience of 3 years in Dukhan QP have been honest and generous employers. Staff accomodation is free and well maintained and all promises have been honoured. Although I can't comment on the Messaid school because I havn't been there, or on the package you are considering, I know some of the people who work there and they are lovely people.
